LTC6957IDD-3#TRPBF

The LTC6957IDD-3#TRPBF is Analog Devices’ industrial-temperature clock distribution device (clock fanout buffer) from the LTC6957 family. It takes a reference clock and fans it out to multiple outputs with low jitter and low skew, suitable for timing-critical digital systems (FPGA/SoC, SerDes, memory interfaces, etc.). The -IDD suffix indicates an industrial temperature grade (typically -40°C to +85°C), and -TRPBF denotes Pb-free, Tape & Reel packaging.
Key points:
- High-performance clock distribution with low additive jitter and tight skew
- Multi-output fanout with configurable drive/format and per-output enables
- Supports common clock formats and interfaces for digital systems
- Industrial-grade device in Pb-free, tape-and-reel packaging
Applications include clock distribution for FPGAs, processors, high-speed interfaces, and telecom equipment. For exact electrical specs (input range, output formats, drive strength, number of outputs, and power supply), consult the LTC6957 datasheet and the specific -3 variant documentation.

Here are the typical features of LTC6957IDD-3#TRPBF (LTC6957 family), concise:
- High-performance, low-jitter clock synthesizer with integrated PLL/VCO
- Fractional-N and integer-N frequency synthesis for flexible output timing
- Programmable output frequencies via divider/multiplier; multiple output formats
- Outputs configurable for LVCMOS, LVDS, LVPECL (configurable by part)
